Episode 6 of "No Gain, No Love" unravels with an ominous investigation into Hae-yeong's alleged workplace harassment, a scenario she assumes to be Ji-uk's elaborate revenge plot. As if orchestrated by fate, Ji-uk strides in, boldly claiming his role as her husband, instantly transforming the accusations into a lovers' spat, much to the executives' surprise.
In a palatial hospital suite, Ja-yeon jolts awake from a terrifying dream, haunted by memories of her abusive father. There, amidst the serene surroundings, stands Gyu-hyun, a gentle reminder of her ordeal. Insistent on independence, she vows to repay him for his kindness. A compassionate nurse whispers that he had carried her through stormy streets to safety, leaving Ja-yeon with a heartful of gratitude and a renewed sense of obligation. Before departing, Gyu-hyun's humble apology echoes, acknowledging the distress he'd inadvertently caused.
Back at the office, tensions simmer between Hae-yeong and Ji-uk as they grapple with the aftermath of their public scandal. Ji-uk's anger boils over at Hae-yeong's misguided suspicion, prompting her to embark on a trust-building exercise: a daring trust fall. Believing him gone, she stumbles and plummets, only to be miraculously caught by Ji-uk's steady arms, proving her faith unshaken.
Arm in arm, they confront the prying eyes and whispering tongues of their colleagues, turning the tables with a shameless charm, Hae-yeong's masterstroke. But their trials are far from over. Hae-yeong is dealt another blow—Bok Gi-un, her accuser, has tendered his resignation. A colleague's whispered revelation stirs suspicion: Gi-un might be tied to the prestigious Bok family, the company's royal lineage.
Hae-yeong and Ji-uk embark on a journey to Gi-un's abode, where a surprising familiarity unfolds between Ji-uk and the man and his mother. Ji-uk assures Hae-yeong that Gi-un's departure is but a temporary setback, promising his return to work. Yet, amidst the reassurance, a gentle scolding lingers—for Hae-yeong's neglect in nurturing Ji-uk's palate with the warmth of homemade meals.
Later, Hae-yeong vents her frustration to Ji-uk, lamenting the sexist remarks that had infiltrated their surroundings, precisely what she had sought to evade. Ji-uk vows to her, resolute in his commitment not to let her suffer any setback on his account. As Hae-yeong makes her way home, a realization dawns on her: Ji-uk would require a wedding band to adorn his finger at the office. However, upon inquiring at the shop, she discovers to her surprise that Ji-uk had already purchased the very ring she had initially rented.
The next morning, Ji-uk's world is turned upside down when he stumbles upon the enigmatic man seated comfortably in his living room. The stranger brazenly brings up the topic of Ji-uk's wife, even offering to dispose of her presence. Ji-uk, unfazed, reprimands him sharply and then probes if Bok Gi-ho is his mastermind. Despite the man's denial, Ji-uk remains skeptical. As Ji-uk departs, the stranger's whispered phone conversation hints at a connection far removed from Bok Gi-ho's involvement.
At work, Hae-yeong and Ji-uk meet, and she proposes they embark on their daily commute together from now on. Her eyes catch the glint of the ring on his finger, and he, with a fleeting grin, fabricates a tale of renting it. Throughout the day, they both become unwitting recipients of inappropriate remarks, seemingly an ingrained custom within the company's walls.
Post-work, Hae-yeong's mind swirls with questions about Ji-uk's unexpected purchase of the ring. Could he harbor feelings for her? Hui-seong and Ja-yeon offer their theories, suggesting he might have acquired it as a couple's ring with his girlfriend. Ja-yeon then divulges that she's reached a settlement with Gyu-hyun, contingent upon his community service at an orphanage—a place where Ji-uk volunteers as a teacher, accompanied by a young girl named Yu-na.
Their paths cross with Gyu-hyun, who's sentenced to a menial task of washing countless buckets of children's clothes. The orphanage director heaps praise upon Ji-uk, and as Gyu-hyun spends time in Ji-uk's company, he's captivated by the latter's unwavering devotion to the children. As Gyu-hyun exits the orphanage, he encounters Director Eom, the esteemed head of an art gallery, who briefly appears as a cameo reminiscent of Kim Sun-young's character from Her Private Life.
The following morning, Ji-uk arrives to chauffeur Hae-yeong to work. She inquisitively inquires about the existence of a girlfriend in his life, and he playfully quips that his wife holds the sole distinction of being his special someone. As they drive, he treats her to her beloved triangle gimbap for breakfast, their bond deepening with each passing moment. When Ji-uk leans in to gently brush something from her face, their connection becomes palpable. She attempts to broach the subject of the ring once more, but a timely phone call intervenes, sparing him from an immediate response.
Gyu-hyun arrives at work, bracing himself for a surprise press conference he assumes his father has orchestrated. With fiery determination, he storms into a room, ready to confront the situation, only to find himself confronted by Hae-yeong and Ji-uk instead. The real reason for the conference dawns on him: it's about the child abuse issue they've passionately brought to light. Furthermore, they've been invited to share a meal with the chairman's family later, an unexpected twist.
Ji-uk's recognition of Gyu-hyun from their orphanage days deepens as he witnesses the enigmatic figure engaging in conversation with him. Memories resurface, as Ji-uk recalls covertly leaving a smartwatch to capture the voice of the mysterious man after he departed their apartment that morning. Overhearing a phone call that hinted at exploiting Hae-yeong, Ji-uk's concern for her intensifies, prompting him to seek a moment to confide in her.
Their conversation takes an unexpected turn when Hae-yeong inquires if Ji-uk's purchase of a ring is motivated by her. His enigmatic response, "What if I did?" leaves her intrigued yet cautious, reminding him that her work takes precedence and his feelings should remain unspoken if they don't run deep.
As the press conference commences, the duo joins the Bok family for dinner, with Woo-jae and Yi-lin rounding out the guest list. The evening takes on an interrogative tone as Bok Gi-ho delves into Hae-yeong's personal life, his questions verging on the intrusive. When the conversation shifts to Ji-uk, he reveals a bitter truth, branding his father a coward who denied him his identity.
In turn, Ji-uk shares his perspective on Hae-yeong, revealing that it was her strategic mind that initially drew him in. For someone who once felt insignificant, Hae-yeong made him feel valued, a sentiment that resonates deeply.
As the night progresses, a montage of revelry and indulgence ensues, culminating in a surreal scene where Hae-yeong awakens to find herself in bed with Ji-uk—and an unexpected third party, Woo-jae. The shocking realization sends all three into a chorus of startled screams, bringing No Gain No Love Episode 6 to a chaotic climax.
